Converting raw I/Q to dB
(This can also be calculated as $20 \log_{10}$ of the amplitude, but unless you already have the amplitude that wastes a square root operation.)
Units
Remember, dB is a relative figure. … If you just take $10 \log_{10}(I^2 + Q^2)$, then 0 dB corresponds to an amplitude of exactly 1. …
